Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer oil application, in particular to a heat transfer oil operation performance testing device. Background Art

[0002] Heat transfer oil is a kind of special oil with good thermal stability used for indirect heat transfer. It has been widely used in various occasions in recent years because of its uniform heating, accurate temperature control, ability to generate high temperature under low vapor pressure, good heat transfer effect, energy saving, convenient transportation and operation, etc., and its uses and usage are increasing. In the production process of heat transfer oil, in order to accurately understand the stability of its performance and the quality of the heat transfer oil, it is necessary to heat the heat transfer oil to test its physical and chemical indicators such as flash point, acid value, viscosity and carbon residue under the operating state. After long-term heating, the heat transfer oil will oxidize and produce certain coking and precipitation, which will affect the service life of the heat transfer oil and even cause adverse effects such as machine blockage. Therefore, it is necessary to use the running performance test device to test the physical and chemical properties of the heat transfer oil after heating for a period of time and make adjustments to ensure the quality of the finished product.

[0003] The patent with authorization announcement number CN216285283U discloses a heat transfer oil operation performance test device, including a heating chamber, a circulation drive pipe, a waste residue chamber, a test chamber and a recorder. The heating chamber, the circulation drive pipe, the waste residue chamber, the test chamber and the recorder solve the problems that the existing heat transfer oil operation performance test device cannot perform dynamic monitoring, the test results are not comprehensive enough, the precipitation generated during the operation of the heat transfer oil cannot be filtered, the test temperature range is narrow, and the test indicators have little effect in actual use.

[0004] However, the above patents still have the following problems: although the above patents can intercept and filter the waste residue through the screen, the accumulation of waste residue on the surface of the screen will cause the performance of the screen to decline, thereby causing the speed of the thermal oil passing through the screen to decrease, affecting the circulation of the thermal oil. If the screen is taken out and cleaned during the test, it is necessary to discharge all the thermal oil on the inside of the waste residue bin, and even the thermal oil of the entire device needs to be discharged. After the screen is cleaned, the thermal oil must be added again, which is cumbersome. At the same time, when the screen is cleaned, there will be a test gap, which affects the overall test efficiency. Therefore, a thermal oil operation performance test device is proposed to address the above problems. Utility Model Content
